Charlie Mullins, whose business turns over ВЈ15m and employs 160 people, worked as a handyman on the town's Longford Estate, surviving on ВЈ64 a week.
The programme, which airs on Wednesday at 9pm, shows Mullins' eight-day experience on the estate. He worked for three charities - Honey Rose Foundation, Long Lane Nursery and the John Holt Cancer Support Foundation - on various projects, including installing drains, putting up shelving, digging and carpentry.
Mullins said he was shocked by the deprivation, crime and drugs he encounters, as well as the overall lack of hope he witnesses on the estate.
ADVERTISEMENT"It was a grueling week and after some of shocking things I've seen I'd be lying if I said I enjoyed every minute of it," he said.
"This experience really took me back to a past life when I was growing up, and it has also made me realise that in 40 years things really haven't improved for many people."
Following Mullins' work on the estate, John Holt Cancer support's new building is going to be made fully operational by Christmas by a team of tradesmen from Pimlico Plumbers, and another team of Pimlico's engineers will carry out work for Long Lane Nursery to provide them with new buildings, including a new workshop, kitchen and toilet facilities.
